TO ALL WHGM IT MAY CONCERN: I

Be it known that I, Anmumm JOHN Bmrsr'l DI'MORAT, of Philsdelphiu, 'in the county of Philedelphie, State of Pennsylvania, have inrented a new e dimpro'ved Telegraphic Cable; slnd I do hereby declare that the following is a. full ind exeet description thereof, reference being hed-to-zthe eccompnnying dreirings, and to the letters of reference marked thereon.

The nature of my invention consists in the construction of s telegraphic cshlewith one or mote-perfectlyunhroken continuoiis tubesor cylinders, =mede .l y lielicnlly wofind -metsllic stripe, insulated internelly and externally, and soconstrncted that, #whenstrained or stretched, the'conductive .povrer of the cylinder remains unimpaired, and alweys'in s direct line and not spiral; By means of cylinders or tubes, the nuniber of condoctors in one cable may be increased indefinitely, without insn'y of the objections that not! exist in other cshlee' where more than on'econductor is made end attempted to be used. To those trying this csble, the advantages ere so:readily apparent that it is unnecessary to enter into 1 discussion of them. i

To enable others skilled in the art to make and use my invention, I trill proceed to descriheitsconstmction.

I take one or-more steel, iron, or copper, or other me'tell'io Wis-es, es st A, Figure 1, and wind closely around tliis a. strip or 'band of copper, or other-metsl in e spir'el manner, as at B, fig. 1,-snd over the joints of this eplnl covering I wind Another metallic strip be similar manner, but carefully bresking the joints of-the first, be at G, fig. 1. The whole is then covered with thread, gotta perche, lcr other insulating md'teriel, ss'et Rig. '1. If another cylinder is desired, I wind, closely ind spirally Fro more'metellic strips, the second mend breaking the joints of the first, in like manner is the firstcylinder; as at E and E, Figure 2, end this again coated with insulating material, as at F, figQ Z; and this-process is continued until, my desired number of cylinders is attained. Severel'small cihles, like fig. 1 or fig; 2,"mey'l e bound firmly together z .nd' insnleted', snd thoe form a double or compound cable. The vrhole cable is theu'coyered with jute or otherwise protected se in other cables.

What I claim as my invention, and desire Insecure by Letters Potent, is

The construction of s telegraphic cable, by means of insulated tubes or continuous cylinder or cylinders, formed of helicelly wound strips, in such manner are to preserve uninterrupted linen-r conduction in case of etret'c-hing, as herein set fortlnpr any other substantially the some, and which will produce these intended efi'ects.
